If someone with very high blood pressure eats almost no salt, lots of carbs, and very little fat or protein for about three months, their blood pressure might drop by nearly 45 points — this diet could really help people with dangerously high blood pressure.

If someone with very high blood pressure eats almost no salt—less than a pinch a day—their blood pressure drops, and their heart and kidneys might even start healing.

Most people over 50 — even those with normal blood pressure or on blood pressure pills — see their blood pressure drop when they eat less salt.

If you have high blood pressure and eat less salt—cutting from about 4.6 grams down to 1.5–2.4 grams a day—your blood pressure will likely go down a bit, especially if you're older, Black, or have kidney disease or metabolic syndrome.

Eating less salt can help lower your blood pressure a little bit — on average, by about 3-4 points for the top number and 1-2 points for the bottom number, based on studies of many different people.

If you have high blood pressure and eat a diet low in salt plus lots of fruits, veggies, and low-fat dairy, your blood pressure can drop by about 21 points — as much as taking one blood pressure pill.
